miniSIA-1
miniSIA-1 analyzer with Chem-on-Valve™ manifold
Description
Features
The Global FIA miniSIA-1 represents a new generation of instrumentation for the proven Sequential Injection technique. It combines sampling frequency and speed of response of FIA with the robustness and reagent economy of SIA. The key to this new capability is the marrying of the Global FIA milliGAT pump with flow programming. The concept was first described by Ruzicka in the FIA Tutorial.
The system is equipped with a milliGAT pump coupled to a heating coil and Chem-on-Valve™ (COV) monolithic manifold. An extra measure of modularity is built into the COV by making the detector flow cell a bolt-on piece. This means that the same manifold can be configured with a short or long path length absorbance cell, fluorescence cell, chemiluminescence cell, and one of a host of different electrochemical detectors. External instruments such as Atomic Absorption, Inductively Coupled Plasma and Electrospray MS are compatible with miniSIA-1 since the milliGAT pump provides a wide range (6nL/sec to 170 µL/sec) of highly reproducible flow rates over long periods of time.
For spectrophotometry the standard 10 mm uv/vis absorbance cell uses fiber optic (f.o.) cables to pipe light to and from the flow cell. A white LED and a WXe lamp are provided as light sources. The spectrometer is an Ocean Optics USB-4000.
The sample port has an inlet and outlet which meet on the face of the COV rotor. Thus the sample can be primed to the valve without drawing sample into the rest of the manifold where it can be a source of carryover. The sample port can also be primed with the next sample while the present measurement is underway, either manually or by a miniaturized metering pump.

Global FIA Products
In the early days of FIA, the most fertile repository of manifold components was the Chromatographer's laboratory. Since those early days, a whole suite of custom components have been developed for those practicing flow-based analysis. These components are now available commercially as stocked items. Global FIA provides a single source for many of the components needed to equip and maintain a flow-based analysis laboratory.
The range of components offered includes:
- Pumps - milliGAT™, syringe, and others
- Valves - selection, injection, and others
- Tubing - PFA, PEEK, Tygon™, Pharmed™, and others
- Fittings
- Adapters
- Heaters
- Reservoirs and vials
- Gas diffusion and permeation devices
- Solvent extraction components
- Mini-columns and separation cells
- Bead handling devices
- Flow meters, low dead-volume temperature and pressure meters
- A wide range of flow cells (included heated flow cells) and detectors such as photometric (uv and vis), chemiluminescence, fluorescence, amperometric, and potentiometric devices.
In recent years we have added a number of sampling components as well. These include:
- the unique supported capillary membrane sampler (SCMS)
- self-cleaning filters
- sampling probes for sampling slurries, and other heterogeneous samples
- sterile sample probes
- inertia filters also called tangential flow filters
All of these devices are available in the Global FIA store.
